10 really good pictures, maybe.
I used two cameras shooting the nighttime Perseid meteor showers. A Sony a6300 with Olympus 55mm f1.2 lens using an OM to E mount adapter, shooting wide open, four second exposures ISO 1000. The other camera was a Sony a6500 with 16mm f2.8 lens and fisheye adapter, shooting wide open, 25 second exposures ISO 1250. Both cameras were set to manual focus and exposure and continuous shooting, locked on using a wired cable release. Shutter speed was calculated using the 300 Rule to reduce the star trail movement in each picture and exposure adjusted by changing the ISO setting.
Images were recorded continuously for at least two hours each night. The morning after each photo session, I spent hours backing up to an external HD and processing the still images.
Using the Sony Imaging Edge Viewer program, I was able to create time lapse movies from the thousands of exposures as videos that lasted a few seconds to a few minutes, depending on the number of exposures in a session. Meteors streaked partially across the sky. Planes and satellites crossed the entire view region, both moving slower than the meteors.

Using StarStax, I created star tracks that showed the circular movement of the stars around the North star. Meteors, planes, and satellites showed up as straight lines crossing the concentric star paths. The StarStaX photo was compiled from 327 exposures taken over 23 minutes (elapsed time).
Every night I saw spectacular meteors in one direction while the camera lenses were pointed to a different quadrant of the sky. I got about ten really good still shots. The time lapse movies are fun to watch trying to spot the meteors.
It has been about 30 years since I had last done any nighttime photography. Way back in the days when rolls of film were sent off to be processed before you could see what you had as images. So I looked on the internet, read some articles and watched some videos. That is where I found out about the 300 Rule, StarStax and tying a hand warmer to the camera lens to keep it from fogging up.
